Billy Joel and Christie Brinkley's daughter Alexa Ray Joel collapsed on stage and had to be rushed to hospital on Saturday night.

The singer had reportedly told the audience at New York's Café Carlyle that she wasn't feeling well, after hurting her back and neck, but wanted to carry on.

But the show came to an abrupt stop when she collapsed in front of the crowd.

She was laster diagnosed with Vasovagal Syncope, a common cause of fainting, and has since thanked her fans for their support, according to The New York Post's Page Six.

In the statement, released on Monday, the star said: "I wanted to thank everyone for coming out to support me,' she said in a statement released on Monday.

"I was excited and determined to fulfill my final performance and I really wanted to end my run with a bang, but this was not what I had in mind and hope I have the opportunity to make it up to the wonderful audience very soon.

"Thanks for all the concern."

The 28-year-old daughter of musical legend Joel had just completed two weeks of successful performances, with her mum and siblings joining her on stage the night before.

She posted a snap of herself singing before the show and wrote: "It's been a true privilege to relish in the past seven sold-out shows at the Carlyle Hotel."

The condition is not serious but can cause a sudden drop in your heart rate or blood pressure - causing you to collapse.

The star was recently forced to deny plastic surgery rumours, writing on Facebook: "I would just like to add that all of the continuously-circulating rumors that I have had extensive 'face-work' and undergone breast-augmentation surgery is simply and entirely 100% false.

"The only thing I have ever had done is my nose, which I have always been completely candid, honest, and open about."
